The pulp then falls into the chute 8G and thence into the beater. The liquid in the meantime is drained into the tank 81 from whence it pumped to a gravityV feed tank 109. From here the liquid flows into the evaporator 13. Here it is surrounded 'oy the steam jacket and as it 'becomes thicker it is pushed forward by the coni'cyer and flows into the next lower conveyer till it energes from the outlet 101 asa semi-solid.

lWhat is claimed is:

1. ln a paperl pulp making machine, the combination with plurality ot' heaters, heating pipes positioned within said heaters, conreyers for conducting material troni said heaters, and discharge ineans carried by the conveyors for separating the liquid discharged from said heaters from the pulp discharged from the said heaters.

t3. ln a paper pulp making machine, the rcnihination will a pluralituIv of heaters coinprisuigI rasingrs, a pli'iralitj,Y o heating pipes positioned i sa'd casingssaid heating pipes adairted to he rotated within said casings l'or stirring the contents thereof, conveyor ineans associated near the bottoni ot lsaid casingi's 'for eoi'iveying material discharged liroui ysaid resinas to the ilesired point, and discha fc chutes associated with said conrevers Mor separating the liquid dischargeil from said casiugs from the pulp discharged therefrom.

2S. ln a paper gulp inaliinji' inaehii'ic, the combination with a plurality et heating cas- U el@ ings, a plurality oi heater pipes carried within said casing, cach of said casings provided with conical ends, journals carried at the conical ends ofsuch casing, supporting pipes engaging' said i'irst mentioned pipes and passing through said journals, and ineans tor feeding; steam through said supporting' pipes and into said first mentioned pipes for heating the saine.

d. ln a. paper pulp making machine, the combination with a plurality of heaters, a conveyer positioned below said heaters,

1.eans for cutting olf the feed ci" said conreyers from either one of said heaters, discharge chutes coopeil-ating` with4 said con- Teyer for receiving and separating the discharge frein said heaters, and squeezing` rollers coperat-ing with said chutes for sepiarating the liquid :troni the pulp discharged frein said conveyer.

5. .ln ay paper pulp making machin` the combination with a plurality of heaters, a conveyer associated with said-heaters, ch tes cooperating with said conveyors for oirg tially separating the liquid from the pulp, squeezing rollers cooperatingwith aid chutes for separating the pulp freir the liquid discharged from said heaters, and evaporators cooperating` with said chute and squeezing' rollers l'or receiving the dischiu fed liquid for evaporating the saine and aiming the liquid to he disclrargged in a semisolid condition. l

6. in a machine of the class described, the combination with a plurality .ot heaters, means for dischinging` material 'roin said heaters, ineans for separating liquid from the pulp of the material discharged from 'said heaters, a refuse receptacle, a storage receptaclg a gravity feed receptacle, an evaporator having a pipe connection with the feed receptacle, nieans for driving said liquid troni said stora receptacle into the feed receiitace, and means for conveying said material troni said evaporator to a, point et discharge.
